safc Options

[dan4]

i have heard a few ppl rattling on about them but someone one said to me that the safc will send your timing up the spout when it changes the afr ratio....??? can anyone explain a little to me as i dont know a lot about them and three ppl have just bought them in my area but im not so sure they work well and reliably

what do you want to use this on? your NA motor, or with a turbo kit?

the correct air to fuel ratio is already set by your ecu, a piggy back only tries to trick the ecu into doing what you want to do. if you have a turbo kit, your are tricking and fighting your stock ecu to add or take away fuel. the ecu sees that the car is running less/more fuel, and starts to act differently because it thinks the car in under different load conditions.

remember, this is a piggy back, not a full stand alone ecu where u can just change the fuel ,and it wont affect antyhing. any change you make, will alwasy affect the timing of the motor.
